To all whom it may concern:

Be it. known that I, CHARLES M; lrlrzenns, a citizen of the UnitedStates, residing in the city of Newark, in the county of Essex and Stateof New J ersey,have invented certain new and useful Improvements inPhonographs, of which the following is a full, clear, and exactdescription, such as will enable others skilled in the art to which itper- .tains to make, construct, and use the same, reference being had tothe accon'ipanying drawings, and to letters of reference marked thereon,which form a part of this specification.

The object of my invention is to increase the simplicity in constructionand. operation of the phonograph, by decreasing the numher of parts ofwhich the machine is composed, by lessening or avoiding the necessityforadjustmcnt of the various parts in practice, andby increasing theconvenience of manipulation of the machine. To this end, I have mademany changes, all with the objects of increased simplicity, convenience,and efliciency.

Heretofore, it has been cnstomar 1 to rotate the mandrel shaftbydirectly connecting the same with the motor shaft.- by snitable pulleys,belts or gear wheels. One feature of my invention is an improvement uponthis arrangement; and consists in rotating the mandrel shaft withoutdirectly connecting it to the motor shaft. by means of pulleys, belts,gear wheels or the like, by causing said mandrel to rest upon and berotated by frictional engagement with a belt which passes over a. pulleyon the motor shaft. and overa. pair of pulleys and under an idler, whichare conveniently secured in a case upon the top of the machine, and inwhich the mandrel shaft is supported and rotated.

In the accompanying drawings forming a part of this specification,Figure 1 is a side elevation of my improved machine, partly in section.Fig. 2 is a plan view. Figs. 3 and 4 are end elevations of the same; andFig. 5 is a vertical sectional view taken on lines a'-a: of Fig. 1,looking in the direction indicated by the arrow.

Similar letters of reference refer to like parts throughout thespecification and drawmgs. A

In the drawings, a represents the case of the machine andb-the ton. tothe under side I of which is mounted in any convenient manner, a motor 0of the usual type. A casing u:

of any desirable shape is secured to thetop of the machine, and providedwith two small pulleys a and an adjustable idler f. A drirmg pulley g issecured to the motor shaft, over \\-'ll1Ch the belt h passes, whichdrives and also passes-over the pulleys a and undcr' the idler f, whichare located in the casing 11. In the drawings. I have shown an elongatedslot. h in both sides of the casing.

through-which a stud 7L passes. upon which is loosely mounted the idler7', said stud being provided at one end with a knurled nut h". whichtogether with the stud atl'ordsa ready means for changing the verticalposition of the idler, in order to adjust the belt 72-. An adjustablebracket 1' provided with a nut section 1 is cbnvenicnttr mounted uponthe top I) of the machine.

The phonogram -mandrel is mounted upon a shaft /.'-and has extendingfrom one side thereof, the feed screw 1 which is in engagement with the*nut section i. The bracket (Z in its top side, is cutaway at 011, so asto ex iose the bolt l2.

From the oregoing description. it will be seen that the phonogramcarrying shaft is is in no way geared to the motor by gears or belts, ashas been customary heretofore. but that the shaft l simply rests uponthe belt. l1, between the two )ulle' vs c, and is driven by frictionalengagement therewith,

and that the other end of the shaft which is screw-threaded. is mengagement wlth the screw-threaded nutscction 2 by means of which thephonogram cylinder is slowly displaced in the direction indicated by thethe feed screw Z which extends from one end of the phonogram mandrel j.

4 represents a sound box of the usual type, convenientl secured to thetop of the machine, and, esigned to receive a sound horn of the ordinalkind.

From the a ove description, it will be phonogram carrying shaft.

apparent that I have produced a. phonegraph possessin' the features ofadvantage enumerated as esirable, and-I wish it .to

be understood that I donot desire to.be

limited to the exact details of'construction shown and described, asobvious modificain. the art.

I claim: V y

1. In a phonograph, the oombinationof a motor, a .frictionallydrivenphonogram tions will suggest themselves to those skilled carrying shaft,and ,means' arranged upon 3; In a phonograph, the combination of amotor, a frictionally driven phonogram carrying shaft, a supportprovidedwith a nut sectionfor supporting one end of said shaft, and driving and.supportingmeans operated by said motor for supporting and frictionallydriving -.the other end of said 4. 'In a phonograph, thecombination of amotor, a frictionally driven phonograni carrying shaft, a supportprovided with a swiveled nut section for supporting one end of saidshaft, and an adjustable driving and supporting means operated by saidmotor for supporting and frictionally driving theother end of saidphonogram carrying shaft.

5. In a. phonograph, the combination of a motor, alpair of pulleysconnected by a belt with the motor and a phonogram carrying shaftresting upon and supported by said belt and driven by frictional contacttherewith.

6. 'In aphonograph, thecombination of "a motor carrying a pulley, a pairof pulleys mounted in a casing and connected by a belt with the pulleyon-the motor, and a phonogram carrying shaft resting upon and supportedbysaid belt and being driven by frictional engagement therewith.

-7. In a phonograph, the combination'of a motor, a pair' of pulleys andan idler mounted 'in a casing and connected by a belt with themotor,'and a phonogram carrying shaft resting upon and supported by saidbelt and being .gagement therewith. -8. In a phonograph, the combinationof a motor carrying a'pulley, a pair of pulleys mountedin a casing andconnected by a belt with the pulley on the motor, a support providedwith a swiveled nut section and aphonograin carrying shaft resting uponsaid belt and swiveled nut sectionand being grliven by frictionalengagement with said 9. In a phonograph,.the combination of a springmotor, a casing provided with a pair of pulleys and an idler, saidpulleys and idler being connected by a belt withsaid spring'motor, asupport provided with a swiveled nut section and a'phonogram carry:

ing shaft resting. upon said belt and swiveled nut section and beingdriven by frictional engagement with said belt.

10. In a phonograph, the combination of a motor, a pair of pulleys andan adjustable idler mounted in a casing, and connected by.

driven byfrictional .en-

a belt with the motor, a support provided with-a nut sectionand aphonogram carrying shaft resting upon said belt and support andbeingdriven by frictional engagement with said belt;
